Lower Tertiary

The Lower Tertiary is Paleocene in age and known to be the most active age for sand deposition within the deepwater Gulf of Mexico. The trend is generally characterized by older sediments with lower porosities, ultra-deepwater depths, and high bottom-hole pressures. Trend water depths range from 5,000 feet to10,000 feet (1,524 meters to 3,048 meters), while target reservoirs are deeper than 30,000 feet (9,144 meters), have high sand content (as much as 70%), gross thicknesses of greater than 1,000 feet (305 meters), and typically lie underneath thick salt sheets. The extreme conditions of these Lower Tertiary wells are pushing the capabilities of many technologies in exploration, drilling, formation evaluation, well testing and completions. Reservoirs are pushing the technical limits of industry equipment, often requiring equipment designed and qualified to meet high pressure and high temperature (HP/HT) environments.

Halliburton is an industry leader in the Lower Tertiary trend, having provided a wide variety of services in the different discoveries. We work closely with our customers to help address the unique operational challenges in the Lower Tertiary, such as reducing NPT, managing wellbore debris, operating in HP/HT conditions, while delivering safe and reliable operations.
